Michigan has joined the appeal of a federal judge’s decision to restore endangered species protections to the gray wolf.

Animal rights and wildlife groups challenged the de-listing in an effort to stop wolf hunting in Michigan and other Midwestern states. Michigan voters rejected wolf hunting last year – although that referendum was circumvented by the Legislature. However, wildlife groups succeeded in court where they failed politically when a federal judge last month restored the protections.

The coalition pushing state lawmakers to give all workers paid sick days is growing. Groups backing bills introduced in Lansing last month held press conferences in Detroit, Flint and Kalamazoo Monday.

Danielle Atkinson, who directs Mothering Justice, an advocacy group for working moms, was in Grand Rapids. If passed, she says the bills would help more than workers.

“99% of restaurant employees don’t have access to one paid sick day and what that really translates into is restaurant workers going to work sick and getting everyone else sick and it becomes a public health issue,” Atkinson said.

The school buses are running again this afternoon in Ann Arbor. A spokesperson for the Washtenaw Intermediate School District, the agency responsible for operating the district's bus system, has drivers for this afternoon.

Researchers at the Ann Arbor school's College of Engineering have replicated a 3-micron-thick, two-layered block "M" to test a system that they say could be used to deliver drugs at different times and rates or to different parts of the body.
